The artistic/scientific/educational image making efforts at Bell Labs were some of the first to show that electronic digital processing (using the IBM 7094 computer) could be coupled with electronic film recording (using the Stromberg-Carlson 4020 microfilm recorder) could be used to make exciting, high resolution images. With the dozen or so films made between 1963 and 1967, and the many more films after that, they showed that computer animation was a viable activity. Zajac's work, Sinden's films (eg, Force, Mass and Motion) and studies by Noll in the area of stereo pairs (eg, Simulated basilar membrane motion) were some of the earliest contributions to what is now known as scientific visualization.
Turner Whitted arrived at Bell Labs from NC State (PhD - 78), and proceeded to shake the CGI world with an algorithm that could ray-trace a scene in a reasonable amount of time. His film, The Compleat Angler is one of the most mimicked pieces of CGI work ever, as every student that enters the discipline tries to generate a bouncing ray-traced ball sequence. Whitted was also very instrumental in the development of various scan line algorithms, as well as approaches to organizing geometric data for fast rendering. In 1983, Whitted left Bell Labs to establish Numerical Designs, Ltd. in Chapel Hill. NDL was founded with Robert Whitton of Ikonas to develop graphics toolkits for 3D CGI. Key developments of NDL include

CAD software started its migration out of research and into commercial use in the 1970s. Just as in the late 1960s most CAD software continued to be developed by internal groups at large automotive and aerospace manufacturers, often working in conjunction with university research groups. Throughout the decade automotive manufacturers such as: Ford (PDGS), General Motors (CADANCE), Mercedes-Benz (SYRCO), Nissan (CAD-I released in 1977) and Toyota (TINCA released in 1973 by Hiromi Araki's team, CADETT in 1979 also by Hiromi Araki) and aerospace manufacturers such as: Lockheed (CADAM), McDonnell-Douglas (CADD) and Northrop (NCAD, which is still in limited use today), all had large internal CAD software development groups working on proprietary programs.
Most CAD software programs were still 2D replacements for drafting, with the main benefits to manufacturers being: i) reduced drawing errors, and, ii) increased reusability of drawings. One of the most famous of those 2D CAD software programs, and one which still exists (in name only) more than 30 years later, was the CADAM (Computer Augmented Drafting and Manufacturing) system originally developed by the Lockheed aircraft company. In 1975 the French aerospace company, Avions Marcel Dassault, purchased a source-code license of CADAM from Lockheed and in 1977 began developing a 3D CAD software program named CATIA (Computer Aided Three Dimensional Interactive Application) which survives to this day as the most commercially successful CAD software program in current use.

So you see even in the aerospace industry true 3D computer aided design wasn't developed into well after the Apollo missions.

How do you fake 1969 lunar landscape images. And you are confusing post data from pre data.

And what software did they use back then and where did the terrane data come from?
